Gets the value of inputCol or its default value. Returns the documentation of all params with their optionally default values and user-supplied values.Įxtracts the embedded default param values and user-supplied values, and then merges them with extra values from input into a flat param map, where the latter value is used if there exist conflicts, i.e., with ordering: default param values < user-supplied values < extra.įits a model to the input dataset with optional parameters.įits a model to the input dataset for each param map in paramMaps. take ( 1 ) TrueĬlears a param from the param map if it has been explicitly set.Ĭreates a copy of this instance with the same uid and some extra params.Įxplains a single param and returns its name, doc, and optional default value and user-supplied value in a string. save ( modelPath ) > loadedModel = PCAModel. getK () True > modelPath = temp_path + '/pca-model' > model. explainedVariance DenseVector() > pcaPath = temp_path + '/pca' > pca.
